Naphthenic Heat Transfer Fluid
A carefully engineered blend of mineral oils refined by multiple hydrotreatment processes, NF Heat Transfer Fluid exhibits extreme purity and high naphthenic content.
Advantageous interaction between paraffinic content and heightened naphthenic content causes high density with low viscosity. These traits increase the effectiveness of the fluid, providing premium heat transfer for many industries

NF heat transfer fluid has greater thermal stability than competitors.
While natural degradation over the life of any fluid is inevitable, Paratherm NF Heat Transfer Fluid is reinforced by its high naphthenic content. This gives our naphthenic heat transfer fluid an extended operational life when compared to straight paraffinic mineral oil-based fluids. When Paratherm NF eventually degrades, it inherently resists fouling caused by thermal cracking.
Paratherm NF Heat Transfer Fluid is fully certified for use in food and beverage applications
Paratherm NF, US FDA registered as food-grade since 1989, is adherent to all current accepted standards. Certified kosher and Halal and NSF HT-1 registered as a heat transfer fluid with incidental food contact, Paratherm NF is in the highest class of mineral-oil based fluids.
Paratherm NF Heat Transfer Fluid is proven save, even after years of use
Durably non-toxic, independent toxicology testing and chemical analysis has experimentally proven used Paratherm NF fluid as safe as a new charge.
